...pressure is stepped up, the steel block is rotated by a man exerting his full strength at the end of a yard-long lever, equipped with a strain gauge to measure the twisting force. When the lever is rotated through 35°, the distortion in the little disk of material is equal to that in a one-inch cube one of whose faces is theoretically pushed 60 inches out of position...
...over the seas four times a year, penning U. S. inhabitants between its eastern and western mountain ranges. When this cold corpse of a satellite has crept 50% closer, a menacing bulge will be sucked out of its earthward face by terrestrial attraction. It will grow to a giant disk covering one-twentieth of the sky, lighting the night with baleful splendor. The lunar mountains, four miles high, will crack and crumble. Earth will shudder, open tremendous crevasses. The rain of moon fragments, falling as meteorites heated by atmospheric friction, will make steaming cauldrons of the seas, a smoking ruin...
...Ruder showed the junketeers a small permanent magnet made of a new iron alloy containing aluminum, nickel and cobalt, hence called "Alnico." This stuff is so powerfully magnetic that it lifts 60 times its own weight, as was demonstrated when a 55-lb. radio cabinet swung from an Alnico disk of less than a pound. Alnico is being groomed to displace small electromagnets in motors, transformers and loudspeakers, lowering cost and simplifying construction...
...Whitley, a onetime rancher who has a nasal voice, plays his own guitar accompaniments, affects a ten-gallon hat and spurs. Whitley sang the tragic songs for Decca Records. Inc., which last week reported a sale of over 5,000 copies. On one side of the disk was The Last Flight of Wiley Post. Excerpts...
Meanwhile, across the U. S. border in Corning, N. Y., famed Corning Glass Co. cast the telescope's most important part-a 5,000-lb. mirror of Pyrex glass. The disk was 74 in. across, a foot thick. After cooling for three months, it was shipped across the Atlantic to Newcastle-on-Tyne, where Sir Howard Grubb, Parsons & Co., spent a year and a half making a polished concave surface true to the ideal paraboloid curve within two-millionths of an inch. Then it traveled back to the new observatory, where it was laboriously removed from its elaborate packing...
